Troubleshooting is the process of discovering and resolving problems with hardware, software, and other products. The goal of troubleshooting is to diagnose the source of a problem and resolve it. When a piece of hardware or software becomes faulty, unresponsive, or acts in unexpected ways, troubleshooting enables the repair and restoration. Sometimes, a flow diagram is used to represent advice, meaning that each question is followed by a series of other questions, depending on the answer.

Troubleshooting is something that everyone has to do at some point. The more it is done, the better users get at fixing problems. This is why it is important to document all the steps taken, ensuring that other troubleshooters will know what to do if the problem happens again.

How Does Troubleshooting Work?

Troubleshooting is a systematic approach done within one or more phases, depending on the complexity of the problem. The first step involves identifying the most general and obvious possible problems. If none of them apply, they can be narrowed down to more specific issues. However, there can be more than one reason for a problem, which will require a more complex solution. Finally, troubleshooting requires confirmation that the problem has been resolved.

For example, if a monitor won't turn on or displays blank, it is best to start with the most obvious problem. It may not be plugged in or the extension lead or surge protector may not be properly plugged in. If it is properly plugged in, the power cord may be damaged or the connections between the monitor and computer may be loose. Finally, if the monitor still does not turn on, it may be faulty and need replacing or there may be a problem with the graphics card.
